Patented June 23, 1931 UNITED STATES PATENT OFFICE ALBERT LINDSAYDOERING, or GERMANTO N, PENNSYLVANIA, ASSIGNOR T .1. s. THORN COMPANY,or PHILADELPHIA COUNTY, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIAMETALLIC wINDoW sriwcmunn Application filed. December 31,1929. SerialNo. 117,627.

My invention is applicable to what are known as double hung windows,including a jamb frame in which two sash frames are mounted toreciprocate parallel with each. other, and relates particularly to meansfor tween the sash slideways in the jamb frame,-

in cooperative relation with flanges on both sashes. Said sash flangeswhich cooperate with said weathering strip have respective J-shapededges and said weathering strip is I also J-shaped at both of its edgesand carries inthe bights of those edges respective weathering caps ofresilient antifriction metal, each adapted to bear upon opposite sidesof the J bights in said sash flanges. As herein-I after described, eachof said caps'is preferably formed of a strip of bI'OIlZQWhlCh is evo-' Vlutely bent and with its inner edgeengaged in the bight of theJ flangeofthe weathering strip and with its outer edge'free for resilient contactwith the respective sash flanges; whereby the maximum freedom ofmovement of said cap is afforded, without permitting accidentaldisplacement thereof. Preferably, each sash style is provided with twoJ- shaped flanges, andthe flangeswhich are remotefrom said weatheringstrip have similar respective weathering caps.

Said sash flanges are provided wlth means for detachable connection withchains or other flexible connectors from the sash frames to sashcounterbalance weights and, as hereinafter described, the constructionand arrangement are such that removal of ascetlon of said weatheringstrip affords access; g pp s p ll flanges 26 and 27 ex 9 to theconnections between the sash frames tendlng into said grooves 13 and 14;Said and the counterbalancing means, which means are concealed when theweathering strips are in their normal position inthejamb frame. However,that construction and arrangement 1 are claimed in my copendin plicationSerial No. 417380 filed December 30, 1929 for Letters Patent of theUnited States.

My invention includes the various novel features of construction andarrangement" hereinafter more definitely specified.

In said drawings; Fig. I is a plan sectional view of; one side of adouble hung window structure, conveniently embodying my invention. l 1

* Fig. II is a cross sectionalview of the resilient antifriction metalcapping strip, in the form which it assumes when free from the sashflange in which it is shown compressed in Fig. I. A

. Fig. III shows a modified form of Weathering cap affording the minimumamount of frictional contact surface.

Referring I to Fig. I; each of the jamb frames '1 is formed of twopieces of sheet metal 2and ,3 which are preferably detachably connected,as described in my copendng application aforesaid. Said piece 2 has itsopposite edges 5 and 6 bent to J-shape and is pressed intermediate ofits edges to form the outer finish molding 7 and inner finish molding 8.The other jamb piece 3 has its opposite edges 9 and 10 respectivelyfitted in said J-flanges 5 and 6, and is bent intermediate of its widthto form vertically extending grooves 12, 13, ll,'and and is normallyheld in rigid relation with thejamb piece 2 in the position shown,'byvertical series of screws 17 which extend between saidgrooves 1'3 and 14and" are in threaded engagement with respective yoke bars 19 which haveinwardly turned ends 20 and 2l respectively overlapping said J flanges 5and 6, as shown.

Each such jamb is provided with removable weather strip sections 22which are detachably held in rigid relation with said jamb frame "plate2 by screws 24. Each of said weatherin strips 22 is channel shaped,havflanges are J-shaped at their inner edges with their short limbsturned toward each other, and carry respective weathering caps 29 and 30which are precisely alike, but with their free edges 31 and 32 presentedin opposite directions.

Each of said strips 29 and is primarily of the cross sectionalconfiguration shown in Fig. II, being preferably formed of a strip ofprimarily plane antifriction spring metal which has been bent and foldedin the evolute form shown, so that its inner edges 34 may be seated inthe respective J bight of the weathering strip 22.

Said jamb structure is adapted to cooperate with the outer sash 36 andinner sash 37 which are double hung in vertically slidable relationtherewith. Each vertical style of said sash 36 has weathering flanges 38and 39 having J-shaped edges respectively extending in said jamb grooves12 and 13, and each vertical style of said sash 37 has weatheringflanges 41 and 42 having J-shaped edges respectively extending in saidjamb grooves 1 k and 15. Said sash Weathering flanges 39 and 41 embracein their J bights the weathering caps 29 and 30 of said weatheringstrips 22, so that said strip is common to a plurality of sashes whichit maintains in weathering sealed relation with said amb frame whilepermitting the sashes to be sealed therein with the minimum amount offriction.

I also find it convenient to provide each of said sash weatheringflanges 38 and 42 with respective weathering caps 45 and 46, preciselylike said weathering caps 29 and 30 but with their free edges 47 and 48presented in opposite directions.

The effect of such construction and arrangement of the weathering caps29 and 30, 45 and 46 is to permit them to automatically adjustthemselves in weathering contact with the opposite vertical side wallsbetween which they are compressed, with the minimum amount of frictionalresistance to the relative sliding movement of the sash frames 36 and 37in said jamb frame 1.

I prefer to provide said sash weathering flanges 39 and ll with means,for instance the hook bars 51 and 52, for detachable connection withchains or other flexible connectors 53 and 54 from said sash frames 36and 37 to sash counterbalance weights 56 and 57 so that removal of asection of said weathering strip 22 affords access to such connectionsbetween said sash frames and such connterbalancing means, which meansare concealed when the weathering stri s are in their normal position inthe jamb rame, as shown.

However, the construction and arrangement of said weathering caps andthe flanges with which they are engaged, as above described, are suchthat they are adapted to cooperate with any jamb structure havingsuitable grooves therein, regardless of the specific form of the windowframe or the sash eounterbalancing means therein.

Moreover, such a weathering strip as indicated at 22, provided withweathering caps 29 and 30, is adapted for sealing joints between awindow frame and sashes by resilient contact of the weathering edges 31and 32 with the surface of the sashes, regardless of the specificconstruction of the latter.

Moreover, in the form of my invention shown in Fig. III, the weatheringcap 59 is angularly bent instead of being curved, with the advantagethat it affords a minimum area of frictional contact surface with thejamb at its opposite portions 60 and 61. However, it is not as easilymade nor as durable as the curved form of cap above described.

An important advantage of the form of sash styles above described isthat it permits glazing with putty, as distinguished from glazing withstrips of metal secured by screws, which is the usual practice. In orderto glaze with putty, it necessary to have a considerable surface of thestyle extending transversely to the glass for engagement with the putty.Although such a surface might be afforded by making the styles L-shaped(leaving off the sash flanges 38 and t1) such construction would leave aspace between the outer surface of the style and the inner surface ofthe jamb, which would not only be unsightly, but would admit the weatherbetween the upper sash and the amb. There fore, it is not onlyadvantageous to provide the sashes 36 and 37 with the extra flanges 38and 4:1 to cover the crevices which otherwise would be left between thestyles and the jamb, but to afford a double weathering joint for eachsash. Therefore, I desire to broadly claim a window sash with suchdouble weathering means as above described, and particularly such a sashwith means upon one of its weathering flanges to engage a sashcounterbalance.

Therefore, I do not desire to limit myself to the precise details ofconstruction and arrangement herein set forth, as it is obvious thatvarious modifications may be made therein without departing from theessential features of my invention, as defined inthe appended claims.
